Other ureteric obstruction

This code signifies an obstruction within the ureter that is not specifically classified elsewhere. It encompasses various intrinsic or extrinsic factors that impede urine flow from the kidney to the bladder, leading to hydronephrosis or renal impairment if left untreated.

Use this code when documentation indicates ureteric obstruction due to causes such as strictures, calculi (if not specified as impacting other parts of the urinary tract), external compression from tumors, or retroperitoneal fibrosis. It is appropriate when the specific cause of obstruction is known but doesn't have a more precise ICD-9-CM code.

• Ensure documentation clearly states the obstruction is within the ureter and not the renal pelvis or bladder neck.
• Always code the underlying cause of the obstruction first, if known and separately identifiable (e.g., neoplasm, calculus).
• Distinguish from congenital ureteric obstruction (753.29) or obstruction due to calculus specified as renal or bladder.
